Your rights when things go wrong.
If goods are not of merchantable quality or are not fit for their purpose or are not as described the consumer is entitled to a remedy.
If the reason for the complaint is not trivial and is discovered soon after purchase, the consumer is entitled to reject the goods and insist on a full refund provided prompt action is action is taken.
If the goods have been used for some time, or if there is undue delay in making the complaint, or if there is reason to believe that the goods have been accepted, the consumer's entitlement, at best, may be to a repair or to a partial refund.
There are no hard and fast rules as each case has to be considered on its merits.
Repairs…must they be accepted?
Where goods have been used for a time and subsequently prove faulty the right to reject them may be lost. In such circumstances a repair or replacement may be the proper solution. A repair should be permanent. The circumstances of each case point to the appropriate remedy. For example, one cannot expect second-hand or 'shop soiled' goods to be of the same standard as new goods.
